Third, in order to overcome the anticipated difficulty of finding the true "X-mode", a practical method is presented to constitute a "quasi-X-mode" approximately.
To demonstrate the application of this method, a full-scale tail-plane structure has been studied by using simulated "test" modes as a simulated case and using measured modes as a practical case.
We used the left atrial diameter assessment by M-mode echocardiography, a practical, low cost and validated method.
For example, for mobile robots equipped with single omnidirectional camera, or radar and sonar operating in passive listening mode, it is a practical requirement to design control strategies based only on measurements of bearings [6],[7].
LAD assessment by M-mode echocardiography is a practical, low cost and validated method.
This latter way of presenting the fact is one way to instantiate what Stanley and Williamson call a "practical mode of presentation".
An English lecture calls for a different mode of regulation than a practical lesson in surgery.
When you understand the core of the problem, you can build solutions that are truly unique -- just like how Henry Ford invented the assembly line to make cars a practical mode of transportation.
Mode-beam extraction for a practical case of error distribution can be conducted through experimental measurements or computer simulations.
Such interaction will provide the basis for determining how the functions of the new form of political organization will be limited and expanded, the scope of which is "something to be critically and experimentally determined" in democracy as a mode of practical inquiry (Dewey 1927b, 281).
But as Henry Grabar writes in Slate, "ferries are a lot more fun than they are useful;" for most New Yorkers, they remain "irrelevant" as a practical transport mode.
